The figure also reports, as blue dash-dotted lines denoted as “Others”, the envelop of the \(95\%\)  CL sensitivity projections of all the future collider projects that have been considered for the 2020 update of the European Strategy for Particle Physics, summarized in Ref. [1]}. These lines include in particular the sensitivity of very accurate measurements at the EW scale performed at possible future \(e^+e^-\)  Higgs, Electroweak and Top factories. These measurements are not competitive because new physics at \(\Lambda \sim 100\)  TeV produces unobservable one part per million effects on 100 GeV energy processes. High-energy measurements at a 100 TeV proton collider are also included in the dash-dotted lines. They are not competitive either, because the effective parton luminosity at high energy is much lower than the one of a 10 TeV muon collider, as explained in Section . For example the cross-section for the production of an \(e^+e^-\)  pair with more than 9 TeV invariant mass at the FCC-hh is of only 40 ab, while it is of 900 ab at a 10 TeV muon collider. Even with a somewhat higher integrated luminosity, the FCC-hh just does not have enough statistics to compete with a 10 TeV muon collider.
